Boxing results: Keith Thurman takes retirement win over Luis Collazo

KEITH THURMAN, renowned as a power puncher, hadn’t won inside the distance in over year, with both Leonard Bundu and Robert Guerrero extending him 12 rounds. But “One Time” returned to finishing form when Luis Collazo retired after seven rounds, hampered by a bad cut, made all the sweeter for Thurman fighting in Tampa in his home state.

On the undercard Willie Nelson took Tony Harrison’s unbeaten record knocking him out with a heavy right hook.
